A Summary of major Construction Projects

The vast majority of the work to improve railway lines, which impacts on the frequency and journey times info as per the journey guides, is completed over one Sat/Sun period.
So if you can't find a usual route or a train departure online, it can be worth having a look at the links to the national construction work, which you will find below.
You may then have to translate what you'll find, but it can be worth the effort to discover what's occurring and to glean whether you'll need to take a bus for part of the journey, or whether trains are being diverted.
Alterations to the usual service are often not particularly obvious when looking up the journey on a ticket booking service.

The information included below is a guide to the the more extensive construction projects which are impacting on train services for a week or more.
Therefore these are the projects which are good to be aware of if you're planning a rail pass itinerary and want to avoid any hassle, or are wondering why a typical connection isn't available on multiple dates.

Also worth knowing is that many major construction work projects, which require timetable alterations, aren't confirmed until around two months ahead.

These are the upcoming rail construction projects which;

• last more than a weekend, so also impact on Monday to Friday travel
• affect long-distance express trains
• result in trains being diverted, with longer journey times (which impacts on connections)
• Or, are being substituted by buses for part of the journey.

1: The Tauern Railway

A key rail route in Austria, the Tauern Railway, is to be closed for more than six months, for construction work until July 27th.
The Tauern Railway is the main railway route in south-west Austria, as it links Salzburg with Villach and Klagenfurt, but until March 2nd the plan is for express buses to replace trains between Bischofshofen and Spittal-Millstätter.
Though trains will be able to travel beyond Bischofshofen to provide a direct service between Salzburg and the other key destination along the route, which is Bad Gastein.

So until June 27th there will be no trains operating between Bad Gastein and Spittal-Millstätter.
The long distance services which typically travel the length of the Tauern Railway are on these two routes.

1. Frankfurt (Main) - Stuttgart - München Hbf - Salzburg ↔ Bischofshofen - Bad Gastein - Spittal-Millstätter - Villach - Klagenfurt
2. Wien Hbf - St Polten - Linz - Salzburg ↔ Bischofshofen - Bad Gastein - Spittal-Millstätter - Villach - Klagenfurt
   A key function of these trains to/from Wien Hbf is to provide a direct link between both Wien and Linz with Bad Gastein, but during the work these trains will be turned around in Salzburg.

There will be EC trains operating a Frankfurt (Main) - Stuttgart - München Hbf - Salzburg ↔ Bischofshofen - Bad Gastein service, but until June 27th there will be no direct trains between Salzburg and the resort towns on the Worthersee between Villach and Klagenfurt.
The trains taking the Wien - Leoben ↔ Klagenfurt - Villach route are unaffected and it looks as though more of them will have their journeys extended beyond Villach to/from Spittal-Millstätter.

What will be impacted by the work on the Tauern Railway are the daytime rail journeys which link Germany, Salzburg and other destinations in western Austria with Slovenia and Croatia.
The trains on the Frankfurt (Main) - Stuttgart - München Hbf - Salzburg ↔ Bischofshofen - Bad Gastein - Spittal-Millstätter - Villach - Klagenfurt route typically connect at Villach with trains taking a Villach ↔ Lesce-Beld - Ljubljana - Zidane Most - Zagreb - Vinkovici route.

2: Innsbruck ↔ Bregenz

From April 23 (8:30 a.m.) to April 29th (03:00 a.m.) due to construction work west of Ötztal train station long-distance trains will be suspended on part of the route between Innsbruck and Bregenz.
A replacement rail service with buses will be set up, but connections cannot be guaranteed and bicycles cannot be transported.
This route is taken by Railjet (RJX) trains on the Bregenz - Feldkirch - St Anton Landeck-Zams ↔ Innsbruck - Salzburg - Linz - Wien / Vienna route.

3: Vienna / Wien ↔ Salzburg

Due to construction work, long-distance trains will run with modified travel times between Vienna Hbf and Salzburg Hbf from May 12, 2025 to June 5, 2025.
The night trains and long-distance trains will be diverted between Vienna Hbf and St. Pölten Hbf .
Some long-distance trains cannot run and connections cannot be guaranteed.
Due to the construction work, there may be some restrictions when booking seat reservations.

1: Until April 21st buses replace trains between Arlon and Luxembourg.

2: On weekends from April 12th to May 4th most Bruxelles <> Antwerp IC services will be turning around at Antwerpen-Berchem station and won't be calling at Antwerpen-Centraal.

Some trains are cancelled and replaced by buses, or with alternative routes which are up to two hours longer.
A small number of scheduled departures per day are operating to the usual timetable.

3: Until May 4th work is being undertaken between Lyon and Vienne which is impacting on the Lyon - Vienna - Valence-Ville - Avignon-Centre - Arles - Mirimas - Marseille route taken by TER trains.

The Lyon <> Marseille TGV services are not affected.

4: Until June 6th the Clermont Ferrand <> Nimes service is replaced by buses between Langeac and Langogne; and the Clermont Ferrand <> Le Puy service is replaced by buses between Langeac and Le Puy.

• to Bratislava Petrzalka station, which is located on the south bank of the River Danube, which is route, REX6

However, until July 5th, due to construction work by the Slovak Railways (ZSR), trains on line REX8 can't be used between Marchegg station and Bratislava hl.st - A rail replacement service with buses will be set up for some trains between Marchegg and Bratislava.
During this time journeys between Vienna and Bratislava will mainly only be possible by using route REX6 - Though the Railjet train on the Zurich ↔ Bratislava route will be calling at both Bratislava hl.st and Bratislava Petrzalka.

Due to construction work on April 16 / 17th and April 28 / 29th the Zurich / Stuttgart to Zagreb train is cancelled entirely - and in the reverse direction from Zagreb, it will not be available on April 17 /18th and April 29 /30th.
